Active Power Files Shelf Registration Statement 
AUSTIN, TX -- (Marketwired) -- 04/30/13 --  Active Power (NASDAQ:
ACPW) (the "Company"), manufacturer of uninterruptible power supply
(UPS) systems and modular infrastructure solutions, announced today
that it has filed a universal shelf registration statement on Form
S-3 with the Securities and Exchange Commission (the "SEC"). The
shelf registration statement is designed to provide the Company with
greater flexibility to take advantage of financing and other business
opportunities when and if such opportunities arise, subject to market
conditions and the capital requirements of the Company.  
If and when the shelf registration statement is declared effective,
it will permit the Company, from time to time, to offer and sell up
to $50.0 million of common stock, preferred stock, depository shares,
warrants, debt securities, units comprised of any such securities, or
any combination thereof in one or more future public offerings. The
actual amount and type of securities and the terms of those
securities will be determined at the time of sale, if such sale
occurs. At the present time, the Company has no specific use of
proceeds or plans to offer any of the securities covered by the
registration statement.  
A registration statement relating to the securities listed in the
shelf registration statement has been filed with the SEC, but has not
yet become effective. These securities may not be sold, nor may
offers to buy be accepted prior to the time the registration
statement becomes effective. This press release shall not constitute
an offer to sell or the solicitation of an offer to buy, nor shall
there be any sale of these securities in any state in which such
offer, solicitation, or sale would be unlawful prior to registration
or qualification under the securities laws of any such state.
